arXiv:2603.15870v1 Announce Type: new Abstract: We present a Riemannian optimization framework for Hartree-Fock theory formulated directly in the Sobolev space $H^1$. The orthonormality constraints ar…
arXiv:2603.15944v1 Announce Type: new Abstract: Quantum spectroscopy seeks to probe chemical systems using nonclassical light, which has properties that are qualitatively and quantitatively different …
arXiv:2603.16010v1 Announce Type: new Abstract: Open quantum walks (OQWs) constitute a class of quantum walks whose dynamics are entirely driven by interactions with the environment. It is well known …
arXiv:2603.16029v1 Announce Type: new Abstract: We develop a perfectly distributable quantum-classical streaming algorithm that processes signed edges to efficiently estimate the counts of triangles o…
arXiv:2603.16036v1 Announce Type: new Abstract: I introduce a method to generate families of CSS codes with interesting code parameters. The object of study is Coxeter groups, both finite and infinite…
arXiv:2603.16048v1 Announce Type: new Abstract: Monolithic three-dimensional (3D) Paul traps combine the high-precision microfabrication of two-dimensional (2D) chip traps with the deep trapping poten…
arXiv:2603.16049v1 Announce Type: new Abstract: Qudits, the multi-level generalization of qubits, provide a natural extension of the binary paradigm in quantum computation and offer new opportunities …
arXiv:2603.16084v1 Announce Type: new Abstract: We have investigated the geometric phase acquired by a uniformly accelerated two-level atom coupled to vacuum fluctuations of a massless conformal scala…
arXiv:2603.16089v1 Announce Type: new Abstract: We theoretically propose a scheme to realize a $n$-cavity-magnon polariton blockade in a cavity-magnon system by utilizing the Kerr nonlinearity. Cavity…
arXiv:2603.16203v1 Announce Type: new Abstract: Quantum error correction (QEC) is essential for realizing large-scale, fault-tolerant quantum computation, yet its practical implementation remains a ma…
arXiv:2603.16214v1 Announce Type: new Abstract: Non-Hermitian many-body systems can be spectrally unstable, so small perturbations may induce large eigenvalue shifts. The pseudospectrum quantifies thi…
arXiv:2603.16225v1 Announce Type: new Abstract: We analyze qubit-qubit entanglement from an energetic perspective and reveal an energetic trade-off between quantum coherence and entanglement. We decom…
arXiv:2603.16235v1 Announce Type: new Abstract: We directly observe far-field correlations of x-ray photon pairs generated by spontaneous parametric down-conversion (SPDC). Using an energy-resolved, t…
arXiv:2603.16246v1 Announce Type: new Abstract: Cavity optomechanics has enabled slow-to-fast light conversion, but traditional optomechanic systems suffer from limited tunability due to fixed mechani…
arXiv:2603.16297v1 Announce Type: new Abstract: A degenerate string is a sequence of sets of characters. A generalized degenerate (GD) string extends this notion to the sequence of sets of strings, wh…
